Improvement in shingling-brackets

WIN SLOW D. WALKER, OF MARLBOROUGH, MASSACHUSETTS, ASSIGNOR TO HIMSELFAND GEORGE N. GATE, OF SAME PLACE.

IMPROVEMENT IN SHlNGLlNG-BRACKETS.

Specification forming part of Letters Patent No. 214,330, dated April15, 1879; application filed May 11, 1877.

To all whom it may concern.-

Be it known that I, WINsLow D. WALKER, of Marlborough, in the county ofMiddlesex and State of Massachusetts, have invented an ImprovedShingling-Bracket, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification, in which- Figure l is a perspective view ofmy improved shin glin g-bracket. Fig. 2 is a perspective View of aportion of a roof with my improved brackets applied thereto. Fig. 3 is asection through my improved bracket applied to a roof. Fig. 4 is asection on the line a: m of Fig. 3.

My invention has for its object to provide a simple and efficient devicefor supporting a staging upon a roof, for use in shingling, or for otherpurposes; and consists in a bracket having a projectingmetallic strip orarm, which is inserted beneath the shingles, and is provided with astaple or lug, which projects up through the space or joint between twocon tiguous shingles, Where it is secured by a pin or other lockingdevice passing through or attached to it, and bearing on the uppersurface of the shingles, so as to create sufficient friction to preventslipping.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents abracket, which is composed of astrip of metal bent into the form of a triangle, as seen in Fig. 1, oneend of the strip being secured at the corner 0 by solder or otherwise.The other end of the strip projects out from the corner 0 of thebracket, forming an arm, 01, which is provided near its outer extremitywith a staple, c.

When the bracket is to be used, the outer end of the arm d, which istapered to an edge, is inserted beneath the shingles, and the staple eentered within the space or joint between two contiguous shingles of acourse. The bracket is then forced up into the position seen in Figs. 2and 3, and a pin, f, or an ordinary board-nail, is passed through theupper portion of the staple, which projects above the surface of theshingles beneath which the arm d is placed. This pin f when in place, asseen in Figs. 2 and 3, bears upon the surface of the shingles, andserves to lock the bracket in place, as any force or pressure which actsupon the bracket to withdraw it causes the pin to bear on the surface ofthe shingles with increased friction, on account-of their tapering orwedge form, and all liability of slipping is thus avoided.

The central portion, g, of the lower side of the bracket is curvedslightly upward, in order to clear the edge of the shingles at thispoint, and allow the lowercorner of the bracket to have a firm bearingon the roof.

When two or more of these brackets are in place, the staging B, Fig. 3,is so laid as to rest upon and be supported by the upper side, h, ofeach bracket, and this side his provided with an aperture, 1', for thereception of a nail or pin projecting from the under side of thestaging, which is thus prevented from slipping ofi' the bracket.

Instead of the bracket being formed of a strip of metal bent to therequired shape, it may be composed of a solid piece of Wood or othersuitable material, the arm d being made separate and afterwardsecuredthereto.

What 1 claim as my invention, and desire to secure by Letters Patent, asan improvement in shingling-brackets, is-- The bracket A, with its armd, provided with a staple or lug, 0, adapted to project up through thespace between two contiguous shingles on a roof, in combination with apin or other locking device passing through or attached to the staple orlug, and bearing upon the upper surface of the shingles, substantiallyas set forth.

Witness my hand this 8th day of May, A. D. 1877.

WINSLOW D. WALKER.
